RemoteApp & SSO problem, need help

[wodbud]

Hello guys, I need help (again).

I'm working on deploying RDS environment with SSO in my domain.

I need to get:

- remote desktop for all users (SSO of course)

- RD WebAccess (SSO)

- starting apps from .rdp file (SSO too)

 

I configured RDS Role (all services on one server, I don't know if it is correct).

Remote desktop & RD WebAccess work correctly, I've got problem with SSO on domain, and everything on workgroup pc (of course not with sso, it works only in domain .

I deployed two apps: wordpad & paint for testing purposes.

 

I'm testing it on 2 pc's - one in domain, one in workgroup. Both are in the same LAN.

 

Situation on domain pc:

- if started from rdp files, first asks for credentials, then both works, even after restart without asking for login/pass

maybe someone knows why rdp asks for password? I've configured all as here: How to Setup RemoteApp to Connect Without a Password Prompt | Justin Cooney

- if started from rd webaccess is similar situation but credentials are lost after restart

 

On pc in workgroup, both of them gave me the same error, from rd webaccess and from rd files.

Remote Desktop can't connect to the remote computer "myserver.mydomain.local" for one of these reasons:

1) Your user account is not authorized to access the RD Gateway

2) Incorrect format of remote computer (e.g. netbios name instead of ip or fqdn) - it's my translation, not exact error description, pc speaks in polish

 

What could be the reason? Or what I missed in config?

I'll be very grateful for any suggestion.

 

And sorry for my english, don't know if it understandable for english-speaking people (maybe it's something like transylvanian english LOL

small edit: domain pc/rds web access - if I run program which needs admin rights and paint or wordpad again, it asks for login/pass again (that second app of course).
